Azeroth has existed since the first Warcraft: Orcs and Humans launched in 1994 and WOW Classic TBC Gold the following Warcraft two games further built on the narrative and lore. Warcraft 3 has been possibly the most popular of those early games and introduced us to a number of the characters that would go on to play huge roles in World of Warcraft, such as Sylvanas Windrunner, Jaina Proudmore, and Arthas Menethil, among many others.

So when World of Warcraft launched in 2004, all of the lore, background, and places that had been laid out in the earlier Warcraft games were attracted to life in Blizzard's vast MMO.

If you've only got a few hours a week to devote to a MMO, Classic might not be the game for you personally and you might be better off looking at modern Warcraft to fill this Azeroth-shaped hole. Having said that, if you're not especially concerned with endgame content like raiding or max-level dungeons and only want to explore Azeroth because it had been in 2006 then by all means, carry on. But if you want to enjoy everything that Classic has to buy WOW TBC Classic Gold offer, then you should be ready to spend a lot of time not only levelling your character but finishing different Attunement quests and grinding reputation to access some of those late-game cases.
